Takotsubo cardiomyopathy (TTC) is uncommon emergency condition usually precipitated by emotional or physical stress and is characterized by near-normal coronary arteries and regional wall motion abnormalities that extend beyond a single coronary vascular territory. Variants of TTC include classic apical ballooning syndrome and less commonly, mid, basal, and biventricular variants. Cardiac arrest is an uncommon complication of TTC. ⋯ All 3 patients had normal QTc interval and were found to have normal coronary arteries on cardiac catheterization at presentation. Mid ventricular TTC was confirmed on contrast left ventriculography and echocardiography. Cardiac arrest myocarditis was ruled out by myocardial biopsy in 2 deceased patients and by cardiac magnetic resonance imaging in the one who survived.

To identify and evaluate the volume, nature, and severity of patient presentations encountered by emergency medical services (EMS) at all mass-gathering events held at or near a southeastern US university. In addition, to compare the existing literature base (single mass-gathering event held in large urban population centers) with a broader variety of events varying in crowd size and locations. ⋯ In this retrospective, descriptive study of a broad range of event type, the most common patient presentations at mass-gathering events were mild in severity, requiring minimal medical intervention. Both transports from the event to a hospital and the occurrence of life threats were uncommon. Our findings are similar to the data found in the existing medical literature.

Randomized Controlled Trial Comparative Study
Ultrasound guidance for radial arterial puncture: a randomized controlled trial.
STUDY OBJECTIVE AND BACKGROUND: Arterial puncture for blood gas analysis is a frequent procedure and could be difficult in the emergency setting. The aim of the study was to compare ultrasonographically guided arterial radial puncture vs conventional sampling. ⋯ Ultrasonographically guided arterial puncture increases the number and duration of implementations. This technique, however, does not alter the patient's pain, the number of immediate complications, or patient and physician satisfaction.

Comparative Study Clinical Trial
A prospective comparison of 3 scoring systems in upper gastrointestinal bleeding.
The clinical severities of upper gastrointestinal bleeding (UGIB) are of a wide variety, ranging from insignificant bleeds to fatal outcomes. Several scoring systems have been designed to identify UGIB high- and low-risk patients. The aim of our study was to compare the Glasgow-Blatchford score (GBS) with the preendoscopic Rockall score (PRS) and the complete Rockall score (CRS) in their utilities in predicting clinical outcomes in patients with UGIB. ⋯ In detecting high-risk patients with acute UGIB, GBS may be a useful risk stratification tool. However, none of the 3 score systems has good performance in predicting rebleeding and 30-day mortality because of low AUCs.
